WebA chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It … WebChirped mirror pairs may be a better solution for applications where these applications would be detrimental. The mirrors in a chirped mirror pair are chosen to have out-of-phase GDD oscillations, leading to an overall oscillation-free GDD over a large bandwidth (Figure 7). This allows for compression of pulse durations down to <3 fs.
